  2. 1. 3D Rotational Angiography of Transplanted Renal Arteries : A Clinical and Experimental Study

    Author : Gaute Hagen; Anders Magnusson; Jonas Wadström; Jarl Jakobsen; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiology; Kidney; transplantation; renal angiography; renal arteries; stenosis or obstruction; imaging; three-dimensional; artifacts; Radiologisk forskning; Radiological research; Radiologisk forskning;

    Abstract : Three-dimensional rotational angiography (3D-RA) is an established method within the field of interventional neuroradiology. The method has also a great potential in other areas with a complicated arterial anatomy. READ MORE

  4. 2. Renal hemodynamics in renal artery stenosis and angiotensin II-dependent hypertension. Pathophysiological and diagnostic aspects

    Author : Aso Saeed; Göteborgs universitet; []
    Keywords : angiotensin II; autoregulation of renal blood flow; color duplex sonography; endothelin-1; oxidative stress; renal artery stenosis; renal hemodynamics; renovascular hypertension;

    Abstract : Patients with renovascular hypertension have a poor renal and cardiovascular prognosis. To improve the care of these patients, we need to increase knowledge about the pathophysiological mechanisms involved. READ MORE

  5. 3. On Renal Artery Stenosis

    Author : Hampus Eklöf; Rickard Nyman; David Bergqvist; Bertil Andrén; Lars Lönn; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiology; Renal artery obstruction; Comparative studies; Contrast media; adverse events; Revascularization; Radiologisk forskning; Radiological research; Radiologisk forskning;

    Abstract : Renal artery stenosis (RAS) is a potentially curable cause of hypertension and azotemia. Besides intra-arterial renal angiography there are several non-invasive techniques utilized to diagnose patients with suspicion of renal artery stenosis. READ MORE

  6. 4. Are gadolinium contrast media really less nephrotoxic than iodine agents in radiographic examinations? A comparison in relation to their ability to attenuate x-rays in a pig model

    Author : Barbara Elmståhl; Malmö Diagnostisk radiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Angiography; Computed tomography; toxicity; Contrast media; Glomerular filtration; Gadolinium; Iodine; Kidney failure; Nephrotoxicity.; Medicin människa och djur ; radiology; Clinical physics; Medicine human and vertebrates ; tomography; medical instrumentation; Diagnostik; Diagnostics; medicinsk instrumentering; tomografi; radiologi; Klinisk fysiologi;

    Abstract : Purpose: To confront the statement that gadolinium contrast media (Gd-CM) are less nephrotoxic than iodine contrast media (I-CM) when used in x-ray angiographic and computed tomographic (CT) examinations. Methods: I) For CT measurements (mean density in Hounsfield numbers) 20-mL syringes filled with I- and Gd-CM at 0.01, 0.02, 0. READ MORE

  7. 5. MRI with MR Angiography in Endovascular Repair of Abdominal Aortic Aneurysms

    Author : Lena Engellau; Malmö Diagnostisk radiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; medical instrumentation; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering; tomography; radiology; Clinical physics; Contrast media complications; Cost analysis; MR velocity mapping; Artefacts; MR imaging safety; MR angiography; MR imaging; Endovascular repair; Stent-graft; aortic; Aneurysm;

    Abstract : The aim of this study was to evaluate MRI with contrast enhanced MR angiography (MRI/CE MRA) as imaging method before and after endovascular repair of abdominal aortic aneurysms (AAA). A 1.5 T scanner was used for all examinations. In this prospective study 26 consecutive patients were included. READ MORE
